Be quiet! PURE POWER 12 M 1000W

Be quiet! PURE POWER 12 M 1000W
The Be quiet! PURE POWER 12 M computer power supply has a power output of 1000W and is designed to power computer builds with higher hardware demands. It meets the ATX 3.0 specification and supports the requirements of PCIe 5.0 graphics cards. The 80 PLUS Gold certification confirms its high energy conversion efficiency. At 50% load, it reaches up to 93.1% efficiency at 230V. Even at full load, the efficiency remains above 90%. Fully modular cabling simplifies installation and reduces obstructions to airflow inside the case. The design, featuring an LLC topology and two 12V rails, ensures stable voltage regulation.
Key technologies of the Be quiet! PURE POWER 12 M 1000W computer power supply
- Total power output of 1000W powers even high-energy-demand builds
- 80 PLUS Gold certification confirms high energy conversion efficiency of up to 93.1%
- 12VHPWR connector powers PCIe 5.0 standard graphics cards
- Quiet fan automatically regulates speed based on current temperature
- LLC technology contributes to voltage stability and precision
- Two separate 12V rails efficiently distribute the load
Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the format is its power output. This indicates the maximum number of watts the power supply can continuously deliver to the components in the computer. It is a good idea to use a web calculator to determine the optimal power output based on your chosen components.
Future-ready with ATX 3.0 and stability
The power supply conforms to the ATX 3.0 standard, which sets requirements for voltage regulation and handling of short-term power spikes. In addition to the native 12VHPWR connector for PCIe 5.0 graphics cards with up to 600W of power, there are also four PCIe 6+2 pin connectors available. This combination ensures compatibility with various graphics cards. The power supply uses a topology with LLC technology, a synchronous rectifier and DC-to-DC converters. This combination regulates voltage and minimises fluctuations on the individual rails. The DC-to-DC converters provide the voltage for the 3.3V and 5V rails.
Quiet operation and installation
Cooling is provided by a 120mm fan with a rifle bearing. Automatic regulation adjusts the fan speed according to the current load and temperature. At low to medium loads, the noise level is below 10 dB(A), and at full power it does not exceed 31.7 dB(A). The fully modular cabling system lets you connect only the necessary cables. The main ATX 24-pin and 12VHPWR power cables are sleeved. The other cables have a flat profile, which makes them easier to route behind the motherboard and in tight spaces. Removing excess cables reduces obstructions to airflow inside the case.
Reliability and comprehensive protection
The use of proven components and a robust design corresponds to an operational lifespan of over 100000 hours at 25°C. The power supply is equipped with two 12V rails that distribute the load between components such as the processor and graphics card. The power supply includes a complete suite of safety protections, which protect the connected components during non-standard operating conditions. These include overvoltage, undervoltage, and overcurrent protection. It also includes overload, short-circuit and over-temperature protection, which automatically shuts down the power supply if it reaches a critical temperature.

80 Plus certification on the European market
The 80 Plus certification was created to objectively assess the efficiency of computer power supplies. This provides users with a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with specific requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC power supply load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
| 80 PLUS Platinum | 92% | 94% | 90% |
| 80 PLUS Titanium | 94% | 96% | 94% |
